CVSS: 5.3
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
How to Fix CVE-2026-103365
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-103365, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"details" : "The Bookly – Online Scheduling and Appointment Booking System plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 28.4 via the classic booking form's Details step. The endpoint bookly_render_details is registered for both wp_ajax and wp_ajax_nopriv, the module overrides csrfTokenValid() to always return true, and Bookly\\Frontend\\Components\\Booking\\InfoText::getCodes() calls UserBookingData::getCustomer() to load the persisted Customer entity keyed solely by the attacker-supplied phone (or email) with no invocation of the plugin's own customerIdentityConfirmed() predicate. When a site owner has placed the supported {client_name}, {client_email}, {client_phone}, or {client_note} placeholders into the Details step's Appearance information text, the matched customer's stored name, email, phone and internal notes are substituted into the returned HTML. This makes it possible for unauthenticated attackers who know only a registered customer's primary phone (or email) to read that customer's stored personal data.",
